Work: Find the solution of equation (80000-x)+(x-x/1.01) = 2330.1 .
Question type: Equation
Solution:Original question:
| ( | 80000 | − | x | ) | + | ( | x | − | x | ÷ | 101 100 | ) | = | 23301 10 |
| Left side of the equation = | 80000 | − | x | + | ( | x | − | x | ÷ | 101 100 | ) |
| = | 80000 | − | x | + | x | − | x | ÷ | 101 100 |
| = | 80000 | − | 100 101 | x |
| 80000 | − | 100 101 | x | = | 23301 10 |
Transposition :
| - | 100 101 | x | = | 23301 10 | − | 80000 |
Combine the items on the right of the equation:
| - | 100 101 | x | = | - | 776699 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
776699 10 | = | 100 101 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
100 101 | x | = | 776699 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 776699 10 | ÷ | 100 101 |
| = | 776699 10 | × | 101 100 |
We obtained :
| x | = | 78446599 1000 |
Convert the result to decimal form :
| x | = | 78446.599 |
